Page 9: Setting Of The Configuration Parameters
10. SETTING OF THE CONFIGURATION PARAMETERS All the controller's configuration parameters are saved in a non-volatile (permanent) internal memory. When the device is switched on for the first time, an error message may be shown in the display due to the lack of a sensor or the fact that the sensor that is connected or not one that is factory-programmed. - Page 10 Table 10.

Notes: (1) – for FiL = 1 the response time is equal to 0.5 s, for FiL = 20 it is equal to at least 4 s. Higher degree of filtration means a "smoother" measured value and a longer response time, which is recommended in the case turbulent measurements (e.g. -

a) basic operating characteristics of outputs b) additional operating characteristics of outputs (applies only to outputs 2 and 3) 12.3. ANALOG OUTPUT The standard of the output signal is determined by parameter 33: AtYP (chapter 10, Table 10). The analog output can work in one of the following modes: retransmission of measurement (parameter 34: outA = rEtr ), manual mode (34: outA = hAnd ) and as an automatic control output (34: FunA = out1 ). -

parameters 35: A-Lo and 36: A-Hi (e.g. 0 mA for the measured value 0 °C when A-Lo = 0 °C, 20 mA for 100 °C when A-Hi = 100 °C and, as appropriate, 10 mA for the half of the range, i.e. 50°C ). Manual operation (chapter 12.8) enables smooth change of the output signal in the range of 0-100% with an increment of 1% and the initial value equal to the last value in the automatic mode (measurement retransmission or control mode, applies to the controller firmware release starting from u-13, which is displayed when power is... -
Page 16: Automatic Pid Parameter Selection
12.5. AUTOMATIC PID PARAMETER SELECTION The first step to use the PID parameter selection function is to choose the type of tuning (parameter 37: tunE , chapter 10). The tuning is started automatically when the control starts (after the power supply is switched on, and by pressing the [F] function button, when parameter 50: Func = StSP , chapter 9.1). -
